2, the wall seepage, generally manifested in the top and bottom of the wall and moldy at the internal corner;

3. The air humidity is too high, resulting in moldy wallpaper;

Question 5: The ceiling is moldy and difficult to clean. Is there any good way? Latex paint itself is mildew-proof and moisture-proof. As for the moldy wall you mentioned, there is only one reason, that is, there is moisture inside the wall, which means that the moisture comes from inside the wall. It was not sucked in from the surface of latex paint. Moisturizing will not be moldy, but the humidity at home is high and the air is not circulating, which leads to moldy latex paint. Otherwise, those exterior wall latex paints are exposed to the sun and rain every day, and they are all finished. For latex paint with good quality and excellent construction, you can directly wipe off the mold with foam cloth. But be sure to remove the moisture from the wall or it will grow mildew. If you want to redecorate, you must also solve the problem of humidity. Dry the wet wall thoroughly before construction. As for good latex paint, I think you should have heard of it.

1. It is true that the area where the house is located belongs to a hot and humid climate, and the perennial hot and humid environment leads to mildew of sticky rice starch glue, a high nutrient substance of wall paint or wallpaper.

2. The wall is wet, and the construction starts before the wall is completely dry, which is easy to get moldy. In this case, the whole wall will be moldy and serious.

3. The inner wall is wet due to water seepage or moisture regain, and it will be moldy in high temperature environment. This situation also includes indoor heating or air conditioning in winter, which leads to a large temperature difference between the inside and outside of the wall and makes the inner wall wet and sweaty.

4. In order to control the cost, the quality of paint or wallpaper glue is poor, and there is no mildew inhibitor or even ordinary bactericide in it.

Second, knowing the cause of mildew, how should we prevent the wall from mildew?

1. First, paint or wallpaper should be brushed before construction. For example, it will take a summer after the house is built, which at least ensures that the moisture content of the wall does not exceed the standard and will not cause the wall to "sweat".

Don't draw stickers on Huangmeitian every year. If the wallpaper is just finished in a hot and humid environment, it will be moldy in a few days, which makes people unprepared.

3. Whether paint or wallpaper glue contains mildew inhibitor, Mrs. Grey mildew inhibitor must be added. The added amount of this mildew inhibitor concentrated solution is very small, about 0.5%, but it can really ensure that the glue is not moldy, even in the hot and humid climate all the year round. Explain here that the action principle of mildew inhibitor is to kill fungal spores such as mold, prevent its reproduction from the source, and protect the substrate from fungal spores for a long time. Especially in the southeast coastal areas where the climate is hot and humid all the year round, we must pay attention to this once and for all. Many decoration companies are already using this method, but most of them don't know it.

4. At ordinary times, the home should be ventilated and dry. Don't spend your parents' time in extremely hot and humid environment, especially when it rains. Close the doors and windows and ventilate the dry environment on sunny days, which is beneficial to protect the wall.

5. If it is wallpaper, try not to choose airtight PVC, but choose breathable materials with better quality, such as non-woven fabrics.

Third, how to deal with the moldy wall? How to solve moldy wall?

1. If the mildew is not serious, it can be wiped off with a rag. You can use soapy water or other cleaning agents, and then buy Mrs. Grey's mildew inhibitor from Taobao. For the direct use of spray, the concentrated solution should be diluted with water, and it can only play a certain role after being treated with mildew inhibitor. But in the end, we must find the reason and solve the problem from the source. Usually pay attention to the ventilation and dryness of the home and maintain a good environment. If the humidity is high, consider air conditioning dehumidification.

2. If it is moldy, it is recommended to redo the wall. Pay attention to the mildew-proof measures above when doing it, and don't bleach it with bleach. Those strong oxidizing things will lead to overall fading and corrosion, mildew again and again, and the side effects are so great. Give up as soon as possible.
